Read all instructions thoroughly Save these instructions SAFETY GUIDELINES Safety guidelines for power tools Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term power tool in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Work area safety Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks, which may ignite the dust or fumes. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
6 SAFETY GUIDELINES 7 Electrical safety Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tools in a damp location is unavoidable, use a ground-fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock. Personal safety Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. Prevent unintentional starting. Ensure that the switch is in the off-position before connecting to power source or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. If devices are provided for the connection of dust extraction and collection facilities, ensure that these are connected and properly used. Use of dust collection devices can reduce dust-related hazards. Power tool use and care Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and more safely at the rate for which it was designed. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control; Use the power tool, accessories, tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. Service Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. Special safety rules for sanders Hold the power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. If a cutting accessory contacts a live wire, it may cause the exposed metal parts of the power tool to become live and shock the operator. The label on your tool may include the following symbols. The symbols and their definitions are as follows: V... Volts A... Amperes Hz... Hertz W... Watts min... Minutes... Alternating current... Direct current n 0... No-load speed... Class II Construction /min... Revolutions or reciprocation per minute... Grounding terminal BPM... Beats per minute... WARNING To reduce the risk of injury, user must read instruction manual.

10 IMPORTANT INFORMATION 11 IMPORTANT INFORMATION Before attempting to use this sander, familiarize yourself with of all its operating features and safety requirements. This sander is designed to sand wood surfaces and to remove lacquer, varnish and other types of coating on wood. Sandpaper sheets This sander uses 1/4 sheet sandpaper, which can be cut from standard (228 x 280 mm) sandpaper sheets. For rough sanding, use coarse grit sandpaper. For smooth or final sanding, use fine grit sandpaper. ASSEMBLY INSTRUCTION Attaching sandpaper (fig 1) 1. Unplug the sander. 2. Disengage the paper clamp by pushing the wire clamp on the side of the sanding pad towards the sander s body. 3. Line up the edge of the sandpaper with the edge of the sanding pad. Insert the sandpaper under the clamp (see fig 1). To lock the sandpaper in place, engage the clamp. 4. Disengage the clamp on the other side of the sander. Stretch the sandpaper tightly over the foam pad and insert the outer edge under the clamp at the rear of the sander (see fig 1). 5. Line up the edge of the sandpaper with the edge of the sanding pad. To lock the sandpaper in place, engage the clamp. This sander provides fast, smooth final finishes. This model can sand flush on all three sides of the tool to get into tight places typical of cabinets, desks and shelving. Using the punch plate (fig 2) After the sandpaper has been clamped to the sanding pad, use the punch plate to punch the vacuum holes into the sheet. 1. Align the punch plate with the sanding pad and push down on the sander until the punch plate pierces the sandpaper (see fig 2). 2. Remove the punch plate from the sanding pad. fig 1 fig 2 Punch plate Sandpaper clamp ASSEMBLY INSTRUCTIONS Always disconnect the sander from its power supply before attaching or removing sandpaper.
12 ASSEMBLY INSTRUCTIONS Attaching the dust bag (fig 3) To install: Press the dust bag port down on to the slot of the dust chute until the chute s detent fully engages with the holes. To remove: Lift dust bag port up. Empty the dust bag by removing the bag from the sander, and gently tap to remove the dust. fig 3 OPERATING INSTRUCTIONS Turning the tool on and off Push the rocker switch to the left to turn the tool on ON and to the right to turn the tool OFF. 1. Make sure that the workpiece is free of nails and other foreign objects that could tear the sandpaper. 2. Always start the sander before applying it to the workpiece. 3. Move the sander evenly over the entire work surface. The weight of the sander alone is sufficient for normal use. Any excess pressure will alter the sanding action, providing an uneven finish, and cause extra wear to both the sander and sandpaper. 4. Never allow the sander to remain in one place on the work surface for too long or excessive material will be removed. 5. The sander should never be turned off while resting on the workpiece. Lift the sander from the workpiece and then turn it off. 6. Do not use the sander without sandpaper, or the pad will be damaged. 7. For optimum performance, make sure your hand does not cover the air ducts located on the sander, and make sure oil or water does not come in contact with the motor. 13 Operating instructions To reduce the risk of injury, turn the unit off and disconnect it from the power source. An accidental start-up can cause injury. Finish sanding can produce clouds of fine sanding dust that could ignite in the presence of sparks or an open flame. To avoid injury, always use your sander in a well-ventilated area.
14 Operating instructions Sanding tips 1. Starting and stopping the sanding Contact the workpiece with the tool only after it has reached full speed and remove it from the work before turning the switch OFF. Operating in this manner will prolong switch and motor life and will greatly increase the quality of your work. 2. Excessive pressure to the sander may result in an uneven sanding job and premature grit wear. Constant and excessive pressure can cause overheating and possible damage to the motor, as well as premature wear out of the pad. a. Light pressure: recommended for fine work. b. Moderate pressure: recommended for rough work. c. Heavy pressure: does not allow the sand paper to rotate properly. 3. If the surface is rough, start sanding with a coarse grit, then medium grit, and then finish with a fine or extra-fine grit. This procedure will vary with different types of materials and work. 4. Continue to sand with each grit until the surface looks uniform. 5. When going from one grit size to a finer size, do not skip more than two grit sizes. 6. To remove the greatest amount of stock, use a coarse grit and move the sander steadily over the entire surface against the grain as well as with the grain. DO NOT REMAIN IN ONE SPOT TOO LONG. It may remove too much material and uneven sanding will result. 7. Sanding with the grain of the wood gives the smoothest final finish. MAINTENANCE Before cleaning or performing any maintenance, make sure that the sander has been disconnected from the power supply. Keep all ventilation openings clean. Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use a clean cloth to remove dirt, oil and grease. 15 MAINTENANCE Do not let brake fluids, gasoline, petroleum-based products, penetrating oil, etc., come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic. To ensure safety and reliability, all repairs should be performed by a qualified service technician. If the supply cord is damaged, it must be replaced by a specially prepared cord available through the service organization.
